To all whom it may concem:

Be it known"that 1, CHARLES DUoAs, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Tender .Tanks, of which the following is a specification.

U My invention relates to locomotive tender tanks and the like, and especially to the type of tender tank in'which the bottom has upstanding flanges to which superj acent parts are secured. The invention is particularly concerned with the provision and installa tion of dash plates in such tanks to prevent injurious water-hammer effects as a result of rapid starting and stopping of the tender, etc. I aim to facilitate and cheapen the installation of the dash plates in the tank, to make the dash plates and their attachments to the tank structure as strong as possible, and to avoid interference with the necessary water circulation in the tank. How these and other advantages can be attained through my invention will appear from my description hereinafter of the best embodiment known to me. The drawing shows a perspective view of a locomotive tank conveniently embodying m intention, part of the external Structure or shell being broken away and'removed. The tank here shown may be briefly described (with suflicient accuracy for my present purpose) with upstanding flanges 6 at its edges; sides 7 overlapping and secured to said flanges; and a top 8 With downturned flanges 9 at its edges that are also overlapped by the sides 7 and secured to them. The bottom 5 is composed of three longitudinal sections 11, 11, and 12 having along their meeting edges upstanding flanges 15, 15- (formed by the upturned edges of the bottom plates 11, 11, and 12) by which they are" secured together. As a result of this mode of con- 4 struction, the bottom 5 has a couple of upstanding fore and aft internal ribs or flanges 15, 15, which reinforce and stiffen it. Since this mode of construction is no part of my present invention, it-requires no further explanation. Nevertheless, I may here point out that the plates 7 11, 11, and 12 can all be secured to one another by horizontal rivets, and that these rivets and the bottom joints of the tank can all be efl'ectively calked (to stop leaks arising in service) as comprising a bottom 5 without the necessity of lifting the heavy tank off the tender. 1

To obviate straining by unchecked surging of the water fore and aft, it is customary to provide tender tanks of various types with transverse dash plates. Owing to the considerable forces exerted on these dash plates by the water, they need to be very securely and substantially fastened in place. Accordingly, my present invention is especially concerned with the attachment of these dash plates.

As here shown, there are two wing dash plates 16, 16 corresponding in width and transverse location to the forward water legs of the tank and to the plates 11, 11 which form their bottoms. There is also a central or intermediate dash plate 18, corresponding in width and transverse location to the shorter central portion of the tank and to the plate '12.- Each of the dash plates 16, 16 has a horizontal top flange 21 and a couple of vertical side flanges 22, 22, all extending laterally from the plate, and formed by bending its edges at right angles. Similarly, the dash plate 18 has horizontal and vertical laterally extending top and side flan es 23 and 24, 24:. These flanges serve to U reinforce and stiffen the plates 16, 16, and 18 aswell as to provide for their connection to the tank structure.

The dash plates 16, 16 are secured and attached to the tank top 8 by means of rivets 25 extending through said top and the abut ting flanges 21, 21, and to the tank sides 7 by means of rivets 26 extending through said sides and the abutting flanges 22 at the outer sides of said plates. The dash plates 16, 16

are also connected and attached to the tank bottom 5 by means of gusset plates 30 secured to the bottom flanges 15, 15 by horizontal rivets 31 and to the inside dash plate flanges 22, 22 by rivets 32. Similarly, the dash plate 18 is secured and attached to the tank top 8 by means of rivets 33 taking into the flange 23, and is connected or attached to the tank bottom by means of gusset plates 35, 35 riveted to the bottom flanges 15, 15 with horizontal rivets 36 and to the The dash late 18 is, of course, not attached to the tank sides 7 7 at all, but only to the bottom 5 and the top 8. The lower edges of the dash plates 16, 16 and 18 are above the tops of the bottom flanges 15, 15, and

flanges 24, 24 with rivets 37. 1

hence well clear of the tank bottom 5. This not only allows freest fore andaft circulation when the water is low in the tank, but also simplifies and facilitates the work of installing the dash plates.

When the bottom sections 11, 11, and 12,

are riveted together, the gussets 30 and are riveted to their flanges 15, 15 without any holes having been made in them for the rivets 32 or 37 After the sides 7 and the top 8 have been put on and riveted up, and the tank is ready for installation of the baflies or dash plates 16, 16 and 18, said dash plates are flanged and punched with all the rivet holes required in them. In this condition, each dash plate is takeninto the tank and placed in proper position, with its top flange 21 or 23 againstthe tank top 8 and its side flanges 22, 22 or 24, 24 in contact with the tank side 7 and the upstanding gusset 30, or with the two upstanding gussets 35, 35. While temporarily held in position, the dash plate is used as a template for marking the required rivet holes in the tank top and sides and in the gussets. The dash plate having been removed, the holes thus marked are dr1lled,after which the dash plate can be permanently riveted in position with the certainty that it will be properly placed and secured.

The superior accuracy, convenience, and economy of such a construction and mode of installation over former practice will readily be apparent to those skilled in the art. In former practice, the dash plate was secured directly to the tank bottom 5 as well as to the top should be just the right height if the result was to be a good job. Owing to the difliculties of fab'ricatin such structures, however, it was almost impossible to predeten mine the exact internal height of the tank, to say nothing of difliculty in accurately predetermining the height of the dash plate after flanging at both top and bottom edges.

It will be observed, moreover, that the dash plates 16 and 18 greatly strengthen and I stiffen the tank transversely. This stiffening is rendered the more effective by the fact that at the tank bottom '5 the dash plates 16,

18 are attached to the relatively stifl', rigid fore and aftribs 15, 15, which distribute the stresses to the bottom ,without excessive concentration at any one 'point.

I claim:
